AI Technical Summary
Existing milk powder dispensing mechanisms suffer from problems such as milk powder accumulation, making it difficult for the milk powder to fall through the dispensing hole, resulting in high resistance and uneven flow.
It adopts a trumpet-shaped powder feeding screw design, with a finer thread section in the powder storage bin and a coarser thread section in the powder outlet channel. Combined with the drive component, it drives the powder feeding screw to rotate, ensuring smooth delivery of milk powder, which falls through the powder drop hole. Precise control is achieved by using a motor and bevel gear transmission system.
It achieves a low-resistance, smooth milk powder delivery process, ensuring that the milk powder can fall stably and accurately from the powder outlet channel, thus improving the efficiency and reliability of milk powder addition.
